I disagree with your percentages and I wouldn't read my comment as only applying to the accounting team. I was an IT manager (and now business owner) doing budgeting, while that is/involves accounting, I am far away from being an accountant (or accounting clerk). Anyone doing even relatively trivial work in these products on a regular basis will benefit from the greater polish in the MS products compared to LibreOffice; again Google may be the logical and viable competitor in a casual-use, business scenario, but not LibreOffice.
Also, for those that are part of the teams of these managers and that have to collaborate with those that can gain direct advantage from the MS Office products, the MS Office/LibreOffice compatibility is simply quirky. It's not so bad if you're simply consuming the content, format isn't essential, and you're not contributing edits and such, but if format is essential or you are contributing/editing... again, the price of the license is not expensive given the productivity loss of people futzing with output due to incomplete compatibility. Finally, those in the office are more likely to already be familiar with MS operating systems and products. Even on the Mac I believe MS Office is still dominant in the office suite space. The productivity hit during training for a new UX vs. just paying the license is again, not supportive of using LibreOffice in any serious business context.
It is my opinion, so take it for what it's worth, that many will argue for the likes of LibreOffice on philosophical grounds rather than on the basis of the economics or product features/functions. And, in order to make their case, they nonetheless feel they have to rely on utilitarian arguments rather than on the merits of their root philosophical commitment. I don't think that's a useful strategy for that interest group when it's apparent that the value for money is actually there compared to the alternatives. I don't want to say that @jimnotgym is in this camp: I don't know; but I do see a similar commitment and line of reasoning from those I know to be.
